DAC7802KU Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
  • To ensure accurate voltage output, it is essential to use a high-quality voltage reference, such as the Texas Instruments REF5025. Additionally, ensure that the output voltage is buffered with an op-amp, such as the OPA277, to prevent loading effects.
  • The maximum output current of the DAC7802KU is 5mA. Exceeding this current may cause damage to the device or affect its accuracy.
  • The digital inputs of the DAC7802KU are CMOS-compatible and should be driven by a 3.3V or 5V logic signal. Ensure that the input signals are properly terminated and that the input voltage does not exceed the maximum rating of 5.5V.
  • The settling time of the DAC7802KU is typically 10μs, but this can vary depending on the output voltage, load capacitance, and other factors. Ensure that the output voltage has settled before taking a measurement.
